drag and drop the selected option to the right place

Correct Answer

(1) \(-4(-3)^2 - (-2)\),Evaluate exponent first
(2) \(12(3) - (-5)(-3)(-2)\),Multiply or divide first
(3) \(-6^2 - (-6)^2\),Evaluate exponent first
(4) \(40 \div (-4) \cdot 5\),Multiply or divide first

Explanation

Expressions with \((-3)^2\), \(-6^2\), or \((-6)^2\) require evaluating the exponent first (Step 2 of the rule). Expressions with only multiplication/division and no exponents go directly to Step 3.
